在IE中点击转跳，并打开chorme浏览器继续浏览指定页面，IE自定义ocx控件开发

因项目需要，需要开发一个功能：在IE中点击转跳，并打开chorme浏览器继续浏览指定页面。

分析需求后，参考了：

https://www.cnblogs.com/ffjiang/p/7908025.html

https://www.cnblogs.com/yilin/p/csharp-activex.html

后，了解得知可从修改本地注册表配置和IE的actived控件两种方式实现，考虑到本地修改注册表无法使用js脚本打开链接，只能使用超链接转跳，与项目本身情况不符，故考虑自定义一个actived控件实现相关功能。

根据参考文献https://www.cnblogs.com/yilin/p/csharp-activex.html，我开始进行相关尝试：

1.创建接口IObjectSafety，以便让客户端信任自定义控件，其中Guid按照参考文件的要求固定为CB5BDC81-93C1-11CF-8F20-00805F2CD064，没有做修改。

    [ComImport, Guid("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]

    [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]

    public interface IObjectSafety

    {

        [PreserveSig]

        int GetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions);

 

        [PreserveSig()]

        int SetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions);

    }

2.创建基类ActiveXControl

    public abstract class ActiveXControl : IObjectSafety

    {

        #region IObjectSafety 成员

 

        private const string _IID_IDispatch = "{00020400-0000-0000-C000-000000000046}";

        private const string _IID_IDispatchEx = "{a6ef9860-c720-11d0-9337-00a0c90dcaa9}";

        private const string _IID_IPersistStorage = "{0000010A-0000-0000-C000-000000000046}";

        private const string _IID_IPersistStream = "{00000109-0000-0000-C000-000000000046}";

        private const string _IID_IPersistPropertyBag = "{37D84F60-42CB-11CE-8135-00AA004BB851}";

 

        private const int INTERFACESAFE_FOR_UNTRUSTED_CALLER = 0x00000001;

        private const int INTERFACESAFE_FOR_UNTRUSTED_DATA = 0x00000002;

        private const int S_OK = 0;

        private const int E_FAIL = unchecked((int)0x80004005);

        private const int E_NOINTERFACE = unchecked((int)0x80004002);

 

        private bool _fSafeForScripting = true;

        private bool _fSafeForInitializing = true;

 

 

        public int GetInterfaceSafetyOptions(ref Guid riid, ref int pdwSupportedOptions, ref int pdwEnabledOptions)

        {

            int Rslt = E_FAIL;

 

            string strGUID = riid.ToString("B");

            pdwSupportedOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER | INTERFACESAFE_FOR_UNTRUSTED_DATA;

            switch (strGUID)

            {

                case _IID_IDispatch:

                case _IID_IDispatchEx:

                    Rslt = S_OK;

                    pdwEnabledOptions = 0;

                    if (_fSafeForScripting == true)

                        pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER;

                    break;

                case _IID_IPersistStorage:

                case _IID_IPersistStream:

                case _IID_IPersistPropertyBag:

                    Rslt = S_OK;

                    pdwEnabledOptions = 0;

                    if (_fSafeForInitializing == true)

                        pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_DATA;

                    break;

                default:

                    Rslt = E_NOINTERFACE;

                    break;

            }

 

            return Rslt;

        }

 

        public int SetInterfaceSafetyOptions(ref Guid riid, int dwOptionSetMask, int dwEnabledOptions)

        {

            int Rslt = E_FAIL;

 

            string strGUID = riid.ToString("B");

            switch (strGUID)

            {

                case _IID_IDispatch:

                case _IID_IDispatchEx:

                    if (((dwEnabledOptions & dwOptionSetMask) == INTERFACESAFE_FOR_UNTRUSTED_CALLER) &&

                            (_fSafeForScripting == true))

                        Rslt = S_OK;

                    break;

                case _IID_IPersistStorage:

                case _IID_IPersistStream:

                case _IID_IPersistPropertyBag:

                    if (((dwEnabledOptions & dwOptionSetMask) == INTERFACESAFE_FOR_UNTRUSTED_DATA) &&

                            (_fSafeForInitializing == true))

                        Rslt = S_OK;

                    break;

                default:

                    Rslt = E_NOINTERFACE;

                    break;

            }

 

            return Rslt;

        }

 

        #endregion

    }

3.创建具体控件OpenChormeActiveX。指定的Guid值“a8d0d357-df7e-41a4-b963-1db5cfa67873”即为该ActiveX控件的唯一标识，保证其唯一性。

[Guid("a8d0d357-df7e-41a4-b963-1db5cfa67873")]

    public class OpenChormeActiveX:ActiveXControl,IIEProperty

    {

        public void OpenChorme()

        {

            System.Diagnostics.Process.Start("Chrome.exe", "https://blog.csdn.net/sinat_23338865/article/details/65447387");

        }

   }

4.设置集的COM可见，设置类库项目属性->程序集信息->使程序集COM可见

5.在VS2017中下载扩展：Microsoft Visual Studio 2017 Installer Project，并创建一个单独的安装项目工程

6.右键点击新添加的安装项目，依次选择“添加->项目输出”菜单，打开添加项目输出组对话框，并选择ActiveX控件类库“CSharpActiveX”作为主输出

7.双击安装项目检测到的依赖项“Microsoft .NET Framework”，打开安装项目的启动条件界面，选中“.NET Framework”项，打开属性窗口，设置.NET Framework项的Version为“.NET Framework 4.0”

8.选中“主输出来自CSharpActiveX(活动)”项，设置主输出项内容的Register属性值为vsdrpCOM。

9.生成OpenChormeFormIE.msi

10.创建一个新文件夹makecab

11.将以下内容，放在cab.ddf中，放在makecab下

.OPTION   EXPLICIT

.Set Cabinet=on

.Set Compress=on

.Set MaxDiskSize=CDROM

.Set ReservePerCabinetSize=6144

.Set DiskDirectoryTemplate="."

.Set CompressionType=MSZIP

.Set CompressionLevel=7

.Set CompressionMemory=21

.Set CabinetNameTemplate="OpenChormeFormIE.CAB"

"installer.inf"

"OpenChormeFormIE.msi"

12.将以下内容，放在installer.inf，放在makecab下

[Setup Hooks]

hook1=hook1

 

[hook1]

run=msiexec /i %EXTRACT_DIR%\OpenChormeFormIE.msi /qn

 

[Version]

Signature= "$CHICAGO$"

AdvancedInf=2.0

13.将OpenChormeFormIE.msi放在makecab下

14.在放在makecab下，启动cmd，执行makecab.exe  /f "cab.ddf"，生成OpenChormeFormIE.CAB

15.在html页面中，添加：

<object id="cSharpActiveX" classid="clsid:a8d0d357-df7e-41a4-b963-1db5cfa67873" codebase="dll/OpenChormeFormIE.CAB#version=1,0,0" style="display: none;"></object>

 

var o = document.getElementById("cSharpActiveX");

o.OpenChorme();
